Q. State whether true or false.
A stone is tied to a string and is whirled in a horizontal circle. If the string breakes when the tension in it becomes greater that

T

, then the maximun centripetal force that can act on the stone is

2 T

For a body in uniform circular motion, (if we are rotating a stone using our hand tied by a thread ) which all real forces act ? The centripetal force will be because of the tension in the string, but which is the real force that causes the circular motion as centripetal (tension) force acts inwards . so which Real force causes such a motion( as centrifugal force is only imaginary )
